我正在运行owfs
(1线文件系统),其他一些过程仅每隔10秒对温度数据进行采样。现在{linux}框上的powertop
显示owfs
进程每秒有40到50个唤醒事件。我假设owfs
经常出去调查/采样传感器,这就是我看到这些唤醒的原因。
由于我非常热衷于这台小机器的能量消耗(每一点节省都有帮助),我想知道是否有办法减少这种唤醒频率。
答案 0 :(得分:0)
如果您在主机上启动owhttpd
并浏览端口:2121
,您会看到有一个包含超时设置的页面。
您可以尝试调整设置,一旦您满意,请将其放在owfs.conf
文件中。我没有这样做但它应该有用。
以下是我网络上列出的设置/超时选项:
directory
60
ftp
900
ha7
60
network
1
presence
120
serial
5
server
10
stable
300
uncached

volatile
15
w1
30
# Timeouts (all in seconds)
# cache for values that change on their own timeout_volatile = value
# seconds "volatile" values remain in cache
# cache for values that change on command timeout_stable = value
# seconds "stable" values remain in cache
# cache for directory lists (non-alarm) timeout_directory = value
# seconds "directory" values remain in cache
# cache for 1-wire device location timeout_presence = value
# seconds "device presence" (which bus) timeout_serial = value
# seconds to wait for serial response timeout_usb = value
# seconds to wait for USB response timeout_network = value
# seconds to wait for tcp/ip response timeout_ftp = value
# seconds inactivity before closing ftp session
